Field Trip, your guide to the cool, hidden, and unique things in the world around you is now on the iPhone! Field Trip runs in the background on your phone. When you get close to something interesting, it will notify you and if you have a headset or bluetooth connected, it can even read the info to you.
Field Trip can help you learn about everything from local history to the latest and best places to shop, eat, and have fun. You select the local feeds you like and the information pops up on your phone automatically, as you walk next to those places.
